可以避免行人被汽車(chē)撞到的智能耳機(jī)

Pedestrians could soon be safer thanks to smart headphones able to decipher hundreds of street sounds and signal imminent harm.

行人可能很快會(huì)更安全，因?yàn)橹悄芏鷻C(jī)能夠識(shí)別數(shù)百種街道聲音和迫在眉睫的危險(xiǎn)信號(hào)。

Scientists are developing the pioneering pods in order to slash the surging number of pedestrian deaths.

科學(xué)家們正在開(kāi)發(fā)這種開(kāi)創(chuàng)性的耳機(jī)，以減少不斷增加的行人死亡人數(shù)。

The amount of people walking the streets with their faces glued to screens while listening to music — also known as “twalking” — is increasing.

越來(lái)越多的人一邊走在大街上，一邊聽(tīng)著音樂(lè)(也被稱(chēng)為“twalking”)，他們的臉粘在屏幕上。

In the last seven years “twalking” deaths have skyrocketed in the US, with pedestrian fatalities reaching a near 30 year high in 2018.

在過(guò)去的7年里，美國(guó)“騎車(chē)族”的死亡人數(shù)激增，2018年行人死亡人數(shù)達(dá)到近30年來(lái)的最高水平。

A research team is now developing the prototype headphones and testing them on New York’s noisy streets in a bid to reverse the trend.

為了扭轉(zhuǎn)這一趨勢(shì)，一個(gè)研究小組正在開(kāi)發(fā)這款耳機(jī)的原型，并在紐約嘈雜的街道上進(jìn)行測(cè)試。

Dr. Fred Jiang, a professor of electrical engineering at Columbia University, said: “We are exploring a new area in developing an inexpensive and low-power technology that creates an audio-alert mechanism for pedestrians.”

哥倫比亞大學(xué)電氣工程教授Fred Jiang博士說(shuō):“我們正在探索一個(gè)新的領(lǐng)域，開(kāi)發(fā)一種低成本、低功耗的技術(shù)，為行人創(chuàng)建一種聲音警報(bào)機(jī)制。”

The headphones have miniature microphones and intelligent signal processing that detects the sounds of approaching vehicles. If a hazard appears near, the system pings an audio alert to the pedestrian’s headphones to warn them of the threat.

這種耳機(jī)配有微型耳機(jī)和智能信號(hào)處理系統(tǒng)，可以探測(cè)到駛近車(chē)輛的聲音。如果附近出現(xiàn)危險(xiǎn)，系統(tǒng)就會(huì)向行人的耳機(jī)發(fā)出音頻警報(bào)，提醒他們受到威脅。

The scientists, writing in IEEE Internet of Things Journal said the research and development of the smart headphones is complex.

科學(xué)家們?cè)贗EEE物聯(lián)網(wǎng)雜志上撰文稱(chēng)，智能耳機(jī)的研發(fā)非常復(fù)雜。

It involves developing a low-power data “pipeline” to process all the sounds near to the pedestrian.

研發(fā)內(nèi)容包括開(kāi)發(fā)一個(gè)低功耗數(shù)據(jù)“管道”，來(lái)處理行人附近的所有聲音。

The pipeline will contain an integrated circuit that identifies relevant sounds and extracts the correct cues to signal impending danger — all while minimizing battery usage.

這條管道將包含一個(gè)集成電路，可以識(shí)別相關(guān)的聲音，并提取正確的線索來(lái)提示即將到來(lái)的危險(xiǎn)——同時(shí)最大限度地減少電池的使用。

The researchers are also using the most advanced data science techniques to design the high-tech headset.

研究人員還使用最先進(jìn)的數(shù)據(jù)科學(xué)技術(shù)來(lái)設(shè)計(jì)高科技耳機(jī)。

Machine-learning models on the user’s smartphone will classify hundreds of acoustical cues from city streets and nearby vehicles.

用戶智能手機(jī)上的機(jī)器學(xué)習(xí)模型將對(duì)城市街道和附近車(chē)輛發(fā)出的數(shù)百種聲音信號(hào)進(jìn)行分類(lèi)。

The researchers, who have won two awards for their prototype, are now testing it both in the lab and on the chaotic streets of New York.

研究人員已經(jīng)因?yàn)樗麄兊哪Ｐ挖A得了兩個(gè)獎(jiǎng)項(xiàng)，現(xiàn)在他們正在實(shí)驗(yàn)室和紐約混亂的街道上進(jìn)行測(cè)試。
